This study focuses on the relationship between organizational socialization, personal and organizational fit, leadership style and willingness of volunteers' retention. The results indicate that the higher degree of socialization of volunteer officers helps to strengthen the fit between individuals and organizations, and positively and significantly affect their willingness to stay. In addition, the executive leadership style has a positive and significant effect on the mediation among organizational socialization, individual and organizational fit and retention willingness. The findings confirm that, in addition to wage and welfare improvements, the management of the army, such as the establishment of social mechanisms and leadership style, will also contribute to the promotion of military system and the stay of army force volunteers and officers.
